Hello Peter, thanks for the note. I'm not looking for anything fancy. It's just when I'm looking at the following bit of Pycassa docs, it's not 100% clear to me that it won't overwrite the entire row for the key, if I want to simply add an extra column {'foo':'bar'} to the already existing row. I don't care about cross-node consistency at this point.
insert(key, columns[, timestamp][, ttl][, write_consistency_level])ΒΆ Insert or update columns in the row with key key. columns should be a dictionary of columns or super columns to insert or update. If this is a standard column family, columns should look like {column_name: column_value}. If this is a super column family, columns should look like {super_column_name: {sub_column_name: value}} -- View this message in context: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/Is-column-update-column-atomic-or-row-atomic-tp6174445p6179492.html Sent from the cassandra-u...@incubator.apache.org mailing list archive at Nabble.com.
